Thanks Joe,
I'm guessing that would account for the slight amount of difference for
steam.

Bob,

The cutoff was the same for both air and steam, my recollection is 75 %.

" Joe,
Good information. Do you know if the engine was running "valves wide
open"
or if there was a cut off point such as 50% of stroke or etc.; and if
the
same cutoff point was existent in both tests?
